its a real good idea after your warmed up, it will make you concentrate on good ball contact and not just start banging balls around.ive kinda done the same thing at the range,i would hit a drive and depending on results my next shot would be a mid to long iron or a wedge shot that always misses green so i have to chip or flop one. if i miss hitt any one of the shots bad id work on that club for about ten balls then do the whole sequence over. agood practis routine can do nothing but help.
